externally through NWS dissemination and communication systems.
The text products affected by collaboration testing are the
National Tropical Cyclone Watch/Warning (TCV) products issued
under the following AWIPS Product Identifiers (PIL) and World
Meteorological Organization (WMO) Identifiers (ID):
